Answer:
The Lateral Surface Area is 911.32 square unit and
Total Surface Area is 1361.7 square unit.
Step-by-step explanation:
For a given Cone
Radius (r) = 12
Height (h) = 21
<u>For Lateral Surface Area</u>
<h3>
<u>Formula</u><u>:</u> </h3>
A = πr√r² + h²
A = 3.14 × 12 × √(12)² + (21)²
A = 3.14 × 12 × √144 + 441
A = 3.14 × 12 × √585
A = 37.68 × 24.18
A = 911.32 square unit
Now,
<u>For</u><u> </u><u>Total</u><u> Surface Area</u>
<h3><u>Formula:</u></h3>
A = πrl + πr²
For Slant height (l)
l² = r² + h²
l² = (12)² + (21)²
l² = 144 + 441
l² = 585
l = 24.18
So,
A = πrl + πr²
A = πr(l + r)
A = 3.14 × 12 × (24.14 + 12)
A = 3.14 × 12 × 36.14
A = 1361.7 square unit
Thus, The <u>Lateral Surface Area</u> is 911.32 square unit and <u>T</u><u>otal Surface Area</u> is 1361.7 square unit.

Answer: 3
Step-by-step explanation:
Let's create a model first.
The initial fee is $19 (this is our y intercept or b)
And the pay per is $4 (this is our variable or m)
y=mx+b
y= 4x+19
To find out what the maximum number of events someone can attend for $31, we plug in different number for the x value until it's less than or equal to $31
In this case, plugging in 3 for x gives us exactly $31
y=4(3)+19= 31
